The compressive dynamic behaviour of normal concrete has been experimentally investigated. Two concrete grades (C25/30, C50/60) have been examined using 100mm cubic specimens with a maximum aggregate size of 16mm. Three testing conditions, i.e., static, intermediate strain-rate and higher strain-rate, have been implemented. For the faster velocities of deformation, Hopkinson bar techniques have been employed. The entire stress-strain curve, including its softening branch, is being constructed. The results clearly show that concrete exhibits strong sensitivity to strain-rate
